TRZ 4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and Concentration, AdBlue, DEF and Industrial Battery Fluid

Je fais du Kombucha et je voulais savoir si il y avait beaucoup de sucre. Après avoir testé avec des boissons zéro sucres et boissons très sucrées, j'ai pu vérifier que ça fonctionne très bien. Et ça vient avec un petit tournevis pour régler la lecture et une pipette pour extraire et déposer le liquide sur la plaque de lecture. Excellent produit.

I keep buying these for our HVAC technicians to determine how much glycol is circulating in boiler systems for radiant heat and snow melt systems.They work really well, even for people with glasses. And since they are reasonably priced, I do not get too upset if a technician loses one or forgets it on the job site.

I was impressed with how easy this was. I have a hydronic floor heating system and had to add (distilled) water to it since it had slowly burped some out. I needed to know the freeze protection level, and this was easy to use and gave me a reading that seemed exactly where it should have been. I plan to flush the system next summer and this will come in handy for setting the dilution for the glycol since I do not know the total capacity of the system. It was easy to read and is a nice tool to have for this use.

The refractometer works well, It was zeroed properly when it arrived and seems to be accurate. (I say seems because I have no means to be certain beyond trying straight glycol and water). My only complaint is that I wish the refractometer had a built in light source as it can be tricky to use with a flashlight.
